This is a guide to creating a Family tree that can be viewed in a web-browser in a convenient way by allowing zoom in/out and navigating the image of the tree.

  1. Install swftools: [1]
  2. use the Graphviz plugin to generate a graphical report (see [2])
  3. If the report image is called "report.png", execute "png2swf -o report.swf report.swf" on the command line.
  4. There should now be a file report.swf, that can be opened in any browser with a flash-plugin. In my case (firefox, winows XP), I can zoom by right-clicking in the image and choosing zoom in from the menu, and I can navigate by "dragging the image" inside the window with my mouse.

I did this with the result of Example 2 on [3], adn the resulting file may be available here soon. I named it ancestorsAndDescedants.swf.


  • It is also possible to use javascript to add zooming by moving the mouse wheel, but he who did it does not remember how at the moment.
  • The .dot file generated in example 3 on [4] seems to contain the web-page addresses to the personal pages of the "Narrative Webpage" report pages, and it would be nice to have links from inside the flash-application to the personal homepages. I do not know if this is possible.
